One approach to improve the targeted therapeutic efficiency of lung cancer is to deliver drugs using nano-scaled systems. In this study, RGD peptide-modified, paclitaxel (PTX) prodrug-based, dual-drugs loaded, and redox-sensitive lipid-polymer nanoparticles were developed and the in vitro and in vivo antitumor efficiency was evaluated in lung cancer cells and tumor bearing animal models. RGD-modified PTX and cisplatin (CDDP) loaded LPNs (RGD-ss-PTX/CDDP LPNs) have sizes around 190 nm, and zeta potentials of - 35 mV. The half-maximal inhibitory concentration (IC50) values were 26.7 and 75.3 mu g/mL for drugs loaded LPNs and free drugs combination, which indicates significantly higher antitumor activity of LPNs than free drugs. RGD-ss-PTX/CDDP LPNs also exhibited the best antitumor efficiency in vivo, which inhibited the tumor size of mice from 1486 mm(3) to 263 mm(3). The results illustrated that the system could successfully load drugs and achieve synergistic combination lung cancer treatment efficiency with lower systemic toxicity compared with free drugs counterparts. The resulting system could be facilitated as a promising targeted nanomedicine for the treatment of lung cancer.
